Behavior of Wood-Concrete Composite Beams
Publication: Journal of the Structural Division
Volume 96, Issue 10
Abstract
Thirteen wood-concrete composite T-beams were fabricated and tested. Epoxy resin was used to bond the wood web to the concrete flange. By proper design, it was possible to stress the concrete in compression and the wood in tension as long as the bond between wood and concrete remained effective. It was found that the beams function as composite sections and carry substantial loads before failure. Four failure modes are identified: Sliding shear, beam shear, tensile wood failure and concrete compressive failure. Beams glued while the concrete was fresh performed at least as well as beams glued after the concrete had set. Longitudinal nails used as additional shear connectors substantially increase the horizontal shear resistance between wood and concrete. Reinforcing wood strips also increase the sliding shear resistance. The effect of other variables remain to be considered.
